Tips on using an
anvil for accurate hardness testing

To keep the test specimen stable and provide
support, always use the smallest anvil possible.

When using test blocks, a pedestal spot anvil
is recommended.

Always ensure that the anvil"™s top surface
and its supporting contact surface are free of dirt, swarf, oil or corrosion.

If the indentor or other object has left
a mark on the anvil test surface or seat, the anvil will cause false readings
and should be replaced.

Pedestal spot anvil

The ¸ 10mm spot anvil is used with small parts and
sheet metal where not much support is required.
This anvil should be used with test blocks.

Cylindrical anvil

This anvil is designed to support cylindrical work and has a capacity
of 50mm to 203mm (2"-8"). A smaller version is also available
from 6mm to 76mm (1/4"-3").

Eyeball anvil

Mounted on an elevating screw, this anvil is designed for test pieces
that have a slight taper. The ball is clamped into position by a clamping
nut which allows the indentor to come into contact with a flat surface.

Clamping protection nose

Device to be mounted on indentor head, to keep the specimen
in place by internal spring force, and to protect the indentor against
collision.

Testing table large

The ¸ 150mm table is the most popular work support for large test
specimens. The table is screwed onto the elevating screw.
The vertical capacity will be reduced by about 25mm.

Flat anvil

The ¸ 60mm flat anvil is used to support many flat specimens perpendicular
to the indentor.

V-anvil

The standard V-anvil is used with cylindrical shaped rods or tubes
of ¸ 6mm or larger. (Not suitable for thin wall or soft tubing).
